.SPEOIFICATION forming part of Letters Patent NO. 703,760, dated July 1,1902. Application filed August 21, 1901. Serial No. 72,8'03. (N0 model.)

To wZZ w/wm it may concern:

Beit known that I, LEWIS A. BROWN, of the city of St. Louis, State ofMissouri, have invented certain new and useful Improvements in Bricks orBlocks, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

This invention relates to bricks or blocks; and it consists of the novelconstruction, combination, and arrangement of parts hereinafter shown,described, and claimed.

One object of this invention is to provide a brick having a metallicplate secured to one or more of its sides.-

Another object is to provide means for securing the plate to a brickwhile the brick is being molded, so that the edges of the plate will beinclosed within the brick, and thereby securely held in position. 7

Figure l is a perspective view of a bric within a mold, showing how thebrickis molded around the edges of the plate. 'Fig. 2 is a perspectiveView of a complete brick. Fig. 3 is a perspective View of a brickhavinga rounded surface. Fig. 4is a perspective view of a brick havingmetallic plates on two of its sides: Fig. 5 is a perspective view of oneend of the plate before being attached to the brick.v

The brick may be composed of any known material and may be cast indifferent forms, as shown. The essential feature of the inventionconsists of a metallic plate 1, having projections 2 extending inwardlyat an angle, and the material composing the brick is molded around thesaid projections 2, thereby holding the plate securelyin position.

In the drawings I have shown the plate located in the bottom of themold, into which the material forming the brick is poured in a plasticstate and allowed to become solid, either assisted by heat or in anyknown manner. The said plate is of equal width with the mold and'brick,and when the brick is completed the said plate covers the entire surfacethereof, forming a' cover which will thoroughly protect the brick fromthe elements.

. If desired, the plate may be provided with an enameled surface and maybe used for ornamental purposes, and in this way a very substantialenameled brick can be provided and the enamel will not become broken soeasily as in the bricks of ordinary construction, in which the enamel issecured directly to the surface of the brick.

In Fig. at I have shown a plate secured to the side and another platesecured to the end, and this form of brick is especially adapted forcorners, while the form shown in Fig. 3, having a rounded surface, maybe usedfor all purposes for which such forms are adapted. These bricksare moldedinsubstantially the same way as above described.

I preferably construct my improved brick or block out of substancecommerciallyknown as perannite and which is formed of the followingprincipal ingredients: sand, cement, sulfur, lampblack, and pigment, andthe process of forming the perannite out of the above ingredients is asfollows:

Theprocess by which the composition is formed consists in reducing theamount of sulfur required to form the composition to a liquid state andmixing therewith the cement, which may be either natural or artificial.The sand before being mixed with the cement and sulfur is heated toahigh temperatureabout 500 Fahrenheit-in order to remove the impuritiesand solidify the mixture after it is placed therein. 'The sand whilestill heated is mixed with the cement and sulfur and forms a solid mass.The mass is then liquefied by applying a temperature of about 750Fahrenheit, and while in this state the lampblack is mixed therewith inorder to render the mass porous and fusible. The temperature of 750 ismaintained for about fifteen minutes, and while being in this state thepigments are added to give the desired color, after which thetemperature is gradually reduced to about 300, at which stage the massbecomes viscid and pliable and in a condition to be poured into the moldto be formed into theobject desired. After the composition is formed asabove specified and'while the tempera ture of said composition is about300 Fahrenheit it is then poured into a suitable form or mold, locatedin thebottom of which is The composition is a metallic face plate.

then allowed to harden by natural process, and this solidificationfirmly holds the metallic plate in the proper position on the face ofthe brick or block.

I claim- 1. The combination with a brick or block, of a metallic platehaving projections rigid with its edges which extend into the body ofthe brick in different directions, substantially as specified.

2. The combination with a brick or block, of a metallic plate having itsedges turned inwardly and inclosed within the brick or block, theexposed surface of the plate being of equal width with the body of thebrick or block and forming the outer surface thereof, substantially asspecified.

3. A brick, having one or more of its surfaces protected by metallicplates, the inner edges of which are turned into and molded within thebrick, substantially as specified.

4. The combination with a brick, of a metallic plate having its edgesturned inwardly and inclosed within'the brick, the said plate formingthe outer surface of the brick, substantially as specified.

5. The combination With a brick, of a plate 1 having its edges 2 turnedinwardly at an incline and inclosed Within the brick, the said platebeing connected thereto while the brick is being molded, substantiallyas specified.

G. The combination with a brick or block composed of sand, cement andsulfur, of a metallic plate having its edges turned inwardly andinclosed within the brick, the said plate forming the outer surface ofthe brick or block, substantially as specified.

7. The combination with a brick or block, of a metallic plate havingprojections extending into the body of the brick in different directionsto prevent detachment of the said plate, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
